High-Quality Food Grade Material Our bento box and accessories are made of high-quality food grade material (Grade 5 PP material), BPA free. The lunch box has no smell, very stain-resistant, drop-proof, and durable material, which is the best meal prep container for kids, and adults. 4 Compartment & with Utensil Set The meal prep containers reusable can satisfy the appetites of both children and adults. Our 1300ml (8.2 x 6.2 x 2.5 inches) lunch box for kids has 4 compartments and a lid with a fork and spoon. Multi-compartment lunch containers for adults provide more balanced meals and nutrition, and the smallest compartments are perfect for sauces. Leakproof Bento Lunch Box The thickened silicone strip on the lid provides good airtightness for the bento lunch box for kids, prevents food smell from leaking, and also prevents the compartment food from penetrating each other. The four-buckle design effectively prevents food from leaking into your bag, even if it is tilted sideways. Microwave and Dishwasher Safe Our lunch box can be heated in a microwave oven, but remember to remove the lid to prevent deformation caused by high temperatures. The salad container for lunch can also be cleaned in the dishwasher, but it is recommended to wash the lid by hand to prevent seasoning from remaining in the silicone gap and keep it waterproof and leak-tight. Easy to Carry The lunch box containers are small, light, and easy to carry, and the buckle design makes them easy to open even for children.
